$ niso pull ruby

29x smaller than Docker

This package is 10 MB vs Docker's 290 MB image. That's 29x less disk space, faster pulls, and a smaller attack surface.

Ruby is a dynamic, open source programming language focused on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. Best known for the Ruby on Rails web framework.

niso packages the Ruby interpreter at 10 MB -- 29x smaller than Docker's 290 MB ruby:3.3-slim image. Includes ruby, gem, bundle, irb, and rdoc. The shared runtime means your Rails apps only ship their Gemfile dependencies, not a full OS and interpreter copy per container.
